Directional conductance of Andreev crystals in hybrid Josephson junction arrays
Anders Enevold Dahl, Andrea Maiani, Max Geier +2
Andreev bound states are coherent electron-hole superpositions that form in a normal metal through repeated Andreev reflection at a superconducting interface. When the length of a…
Interplay of superconductivity and ferromagnetism in ferromagnetic semiconductor-based Josephson junctions
Hirotaka Hara, Lukas Baker, Axel Leblanc +8
The interplay between superconductivity and ferromagnetism has long been pursued as a route to unconventional Josephson effects, yet suitable material platforms remain limited. Her…
Anharmonicity and Charge-Noise Sensitivity of Fraunhofer Qubit
Longyu Ma, Tony Liu, Javad Shabani +3
We present a theory of a flux-tunable superconducting qubit, the "Fraunhofer qubit," based on the Fraunhofer interference in a wide ballistic Josephson junction. As magnetic flux t…
Resource-Efficient Emulation of Majorana Zero Mode Braiding on a Superconducting Trijunction
Rahul Singh, Weixin Lu, Kaelyn J Ferris +1
Topological superconductivity could host quasiparticles that are key candidates for fault-tolerant quantum computation due to their immunity to noise as they obey non-Abelian excha…
Planar Josephson junction devices with narrow superconducting strips: Topological properties and optimization
Purna P. Paudel, Javad Shabani, Tudor D. Stanescu
We study the low-energy physics of planar Josephson junction structures realized in a quasi-two dimensional semiconductor system proximity-coupled to narrow superconducting films.…
